TIL a $120 borescope saved my bacon on a 'no-start' diagnosis
Customer's car had a crank, no start, and all the usual sensors checked out. I snaked the camera down a spark plug hole and found a bent valve staring right back at me, saved hours of pulling the head for nothing. Anyone else have a cheap tool that's paid for itself ten times over?
Yeah, a good multimeter is worth every penny. I keep a basic one in my toolbox just for checking grounds and continuity. It saves so much time chasing electrical gremlins.
